Hacking Dstwo Card Sporadically Not Saving

[CoffeeFiend]

I've had my DStwo card for at least 2 years now, but it suddenly decided not to save my game's progress a few weeks ago. Everything was fine, but when I went to return to my game (a DS game loaded from Bagplug) everything I had done the previous evening hadn't been recorded, despite the system lying to me when I had saved both in-game, and with the save-states. The data from the night before last was still there.

I cleaned the contacts on both the SD card and DSTwo card, and popped it back in. I tested it, and it saved fine.

Last night it did it again, with a GBA game played on the DSTwo's GBA emulator. About 2 hours' progress has disappeared. My game remains as it was, like last night never happened.

Is it the DSTwo card, or my SD card? I bought them both at the same time, and I know my SD card isn't a fake; I bought it in New Zealand's equivalent of Best Buy.

Any help would be appreciated, and thank you!

Move the data from the SD card to a PC and format it and try again. If it does it again try another SD card. if the same issue then try another DS. If all else fails get another DSTWO.

Thanks, it's been working so far. I didn't reply because I was testing it, and holiday crap. I hate it when I find someone with the same problem as me, but their first post is "NVM- FIXED IT."

Thank you for responding, and I'm sorry I didn't sooner.
